LA7567B, 7567BM Notes Sanyo Filters There types filters, which differ piezoelectric substrate material, follows: Lithium tantalate (LiTaO3) filter TSF11s Japan TSF12s Although lithium tantalate filters have temperature coefficient ppm/°C, they suffer from large insertion loss. However, possible, cost increasing number external components required, minimize this insertion loss using matching circuit consisting coils other components filter output. same time minimizing insertion loss, this technique also allows frequency characteristics, level, other aspects varied, thus provides increased circuit design flexibility. Also, since filter reflected wave level minimal, circuit designed with small in-band ripple level. Lithium niobate (LiNbO3) filter TSF52s TSF53s Although lithium niobate filters have high temperature coefficient ppm/°C, they feature insertion loss about lower than that lithium tantalate filters. Accordingly, there need matching circuit filter output. Although in-band ripple somewhat larger than with lithium tantalate filters, since they have impedance small field slew, they relatively immune influences from peripheral circuit components geometry printed circuit board pattern. This allows stable out-of-band trap characteristics acquired. above considerations, lithium tantalate filters used applications Japan that have high frequency, lithium niobate filters used applications that have frequency. Notes Filter Matching filter input circuit matching, rather than matching frequency, flatter video band characteristics acquired designing tuning point vicinity audio carrier rather than near chrominance carrier. situation shown figure right makes easier acquire flat band characteristics than that figure left.

LA7567B, 7567BM Notes Tank Circuits Built-in capacitor tank circuits When power turned heat generated transmitted through printed circuit board tank circuit. this point, coil frame functions heat sink heat dissipated. result, becomes more difficult transmit heat tank circuit's built-in capacitor, influence drift power reduced. Therefore, suffices design circuit that coil capacitor thermal characteristics cancel. Ideally, better coil with core material that temperature coefficient characteristics. External capacitor tank circuits When external capacitor used, heat generated transmitted through printed circuit board directly tank circuit external capacitor. While this capacitor heated relatively early after power turned coil influenced much this heat, result power-on drift increased. Accordingly, coil whose core material temperature coefficient characteristics must used. also desirable capacitor with similarly temperature coefficient characteristics. Note: Applications that external capacitor here must chip capacitor. ordinary capacitor used, problems such oscillator frequency changing with capacitor orientation occur.
